A snowblower assembly for removing snow from a paved surface, such as roadways and airport runways. The snowblower assembly includes a snowblower assembly that defines an open interior that encloses a pair of rotating side augers and a rotating impeller. The snowblower housing includes a lower leading edge that is recessed behind the blade tips of the rotating impeller. The sidewalls of the snowblower housing each include a recessed lower sidewall edge to reduce the buildup of snow within the snowblower housing. A side plate extension is mounted to each of the sidewalls to modify the volume of the open interior defined by the snowblower housing to accommodate different types of snow.

Provided is an all-electric riding greens mower. The mower includes a frame which is supported for movement upon a plurality of ground engaging wheels and upon which are supported a modularly interchangeable power source and a plurality of reel lawn mowers. An electric motor provides driving torque to enable movement of the mower between and over golf course greens or other surfaces to be mowed, electric motors provide driving torque for each of the reel lawn mowers. The interchangeable power source provides electrical energy for driving the electric motors, including the primary mover and the electrical motors for the reel type lawn mowers. The modularly interchangeable power sources may comprise a bank of batteries, a motor/generator set, a fuel cell, or a combination of these. The power source may be easily exchanged in the field for another, freshly charged power source. Exchange occurs using either a fixed change stand or a mobile change stand. The change stands are configured to facilitate exchange by reducing friction caused by the generally weighty power source. The power source is delivered to the fixed stand on towable trailers.

A walk-behind battery-powered lawnmower having an assembly of a reel unit and a traction unit articularly connected together in an arrangement wherein the reel unit can conform in its vertical position to the elevation of the turf which is being mowed. Thus there is an articular connection between the two units, and the reel unit rides up and down in response to the turf undulations. An electric battery is supported on the traction unit, and there is required only an electric wire connection providing the rotation drive power from the battery to the mower reel. Separate electric controls between the battery and to a motor on the traction unit and one on the reel unit provide for operational speed control to thereby select the clip rate of grass cutting in an articular assembly.

A removable battery tray for an electric mower is disclosed. The battery tray fits over the frame of the mower during operation, and can be removed by a hoist or other method in order for the electric mower to continue to operate with another charged set of batteries. The battery tray also has a central power plug that is used for charging and is the only electrical disconnect required when changing the battery tray.

An engine speed control apparatus wherein the upper limit of engine speed can be set and then not be exceeded once a key-operated switch has been activated to an 'off' position. The key can be removed from the switch so that the operator cannot exceed the maximum selected engine speed.

Engine maximum speed limiter

A vehicle steering control system and apparatus for controlling steering radius to prevent vehicle and surface damage and to provide improved low speed vehicle maneuverability. The steering control system and apparatus provides a first controllably limited turning radius range in relation to a first condition and a second controllably limited turning radius range in relation to a second condition. Examples of the first and second conditions include speed related conditions, such as, the actual speed of the vehicle, a selected gear of the vehicle, and manual selection of the turning radius. The system and apparatus includes a dual stroke hydraulic cylinder having a cylinder body housing a hydraulically controllable primary piston. A shaft is attached to and extends from the primary piston, projects through the cylinder body, and connects to the steering linkage of the vehicle. Hydraulic operation of the primary piston transfers forces along the shaft to the linkage. First and second hydraulically controllable stroke limiting stops are positioned at each end of the cylinder body. The stops are hydraulically positionable for limiting the stroke length of the primary piston and the attached shaft. A hydraulic control device is associated with the hydraulic cylinder for operating the primary piston and the first and second stops. A mode selection device is associated with the hydraulic control device selecting a desired mode of operation and thus controllably operating the first and second stops to controllably limit the turning radius range of the steering mechanism of the vehicle.

System and apparatus for limiting vehicle turning radius

An engine speed control apparatus employs a governor responsive to predetermined control input signals for controlling engine speed. An accelerator sensor produces an accelerator control input signal corresponding to the position of an accelerator. A mode selector selects one of a governor mode and a throttle mode, and produces one of a governor mode control input signal and a throttle mode control input signal corresponding to the mode selected. The governor is responsive to the governor mode control input signal for permitting the selection of an upper limit of engine speed within a predetermined range of speeds and thereafter for controlling the engine speed to maintain the engine at this upper limit when the accelerator control signal corresponds to a maximum accelerator position. The governor is responsive to the throttle mode control input signal for permitting the selection of a lower limit of engine speed within a predetermined range and for thereafter controlling the engine speed to maintain the engine at this lower limit of engine speed when the accelerator control signal corresponds to a minimum accelerator position.
